Robust and Efficient Aggregate Query Processing in …

from sensor nodes to the network's sink. In general, aggregate queries can be classified into two categories, duplicate-insensitive and duplicate-sensitive. For duplicate-insensitive aggregations such as MIN and MAX, Silberstein [19] presents a novel query processing algorithm called HAT with the goal of minimizing message
